MicroPython • Re: Pico 2 mqtt quick question on sending binary

Code:

import secretswifi_ssid = secrets.SSIDwifi_password = secrets.PASSWORDmqtt_server = b'secrets.MQTTSERVER'#mqtt_server = b'MQTT_BROKER_URL'mqtt_username = b'BROKER_USERNAME'mqtt_password = b'BROKER_PASSWORD'

Will the mqtt_server = b'secrets.MQTTSERVER' work? Using secrets.py for my internet/pass connection but sending in binary will that work as b'secrets.MQTTSERVER'?

No. That will return the literal string b'secrets.MQTTSERVER'. You can see that by running the following:If the module you're importing defines that as a byte string it will remain a byte string unless you convert it to a "normal" (unicode) string. Either explicitly via bytes.decode() or implicitly depending on how you use it and manipulate it.

You may want to look at the python docs for bytes.decode() and str.edcode().
